This invention relates to phonographs and other recordin machines, and more particularly to dictating and'transcribmg and allied machines.

An object of this invention is to provide an improved record-ejector for freeing theo preparatory to removing the record there;

from. A further object is to prov1de a recordejector having the parts so arranged that the operators thumb ma actuate the e ector while the index and middle fingers are in line with the end, of the record'to engage its inside surface when ejected. V

' A still further object is to provide a record'- ejector having its actuating art so pos1.-

tioned that it does not, ter ere with the 'mandrel of theself-adjusting having spring presseddevices to yieldingly engage and hold the record.

Other features and advantages will hereinafter appear. V

In the accompanying drawing: Y

Figure 1 is a perspective ,view of a dietating machine of the dictaphone typeshowing the operators hand in the act of ejecting the record and removing it from the mandrel.

.Fig. 2 is a planview of the bottom'of the machine frame showing the operating parts of the ejector.

Fig. 3 isha front elevation of the machine showin t e ejector in opera position. The dictating machine shovi' d m the accompanying drawing has a base 10. with vertlcal standards 11 provided with suitable guides 12, upon whlch there is slidably mounted a sound-box carriage 13. The 60 sound-box carria ing'tube 14 whic is supported when out of use upon a, hook 15 at the left-side of the machine. At this side of the machine there is connected witha speak isalso provideda housing 16 having bearings for the shaft 17 of the mandrel 18-which supports the wax-like cylinder or record upon which therecording of the sound is done.

The'mandrel 18 istapered to-fit the tapered inside surface of the record, and is provided witii'a plurality o f spring pressed plungers 19 which frictionally engage the inside surface of the record to securely hold the record on the mandrel.

When the record is bein applied to the machine, it is plilced upon the mandrel, and then gently pushed, by the operators fingers engaging its end, until the other end of the record engages a flange 20 on the "mandrel.

Heretofore, the ejector device provided for freeing the cylinder from the mandrel was mounted on the housing 16 directly beneath the hook 15 for the speaking-tube. This structure, while being itself satisfactory'in operation, nevertheless, was inconvenient. to operate because the speakingtube hanging upon the hook 15 was in the way; and it was necessary for the operator to remove the speaking-tube from the hook. durin the operation of the ejector. Further, wit this form of ejector, it was necessary for the operator'to operate the ejecting-lever with. one hand while holding the fingers of the other hand in line with the mandrel to receive the record when it was ejected. It is the object of this invention vto avoid these difliculties and the following is a description of one exemplary embodiment of this invention.

For-ejecting the record there is provided a plunger 21 supported in the bearing memher or housing 16 to move longitudinally of the machine. The operating end of the plunger 21 has a head 22 so shaped as to pass by the flange 20 but to engage the end of the record w en the plunger 21 is reciprocated. The other end of the pl r 21 isprovided with a hooked portion 23 apted to, engage the notched end 24 of an upstand ing arm 25 forming part of a longitudinally disposed link 26. This link 26 extends below the base 10 of the frame and terminates at a point approximately in line with the end of the mandrel. At this end, the link 26 is connected to a lever 27 by a shouldered screw 28. The lever 27 is fulcrumed upon a stud 29 at the rear of the machine, and at its forward end it is provided with 'anupwardly extending. portion 30 forming a finger-piece by means of which the lever may be operated.

. This, finger-piece extends through a slotted plate 31 covering a suitable opening 32 left in the casting forming the base 10. The ends of the slot in the plate 31 serve as stops for limiting the movement of the lever 27 The parts are held; in their normal posi tlonsby'means ofv a spring34 having one end connected to the link 26 and the other end connected to the lever 27 adjacent the point of connection of the link andJleverJ- The tendencyis for the spring- 34 to pullthe lever 27 to the'left as' seen 111 Fig. 2, and- .since, when the lever moves to the left, the

plunger and the links 26 must also move to the left, the spring maintains the .en

tire device in inoperative position. It should be noted that the spring is not. attached to any part of the frame-work but merely thumb engaging the to the lever system of the ejector and therefore the device may be installed without at-. taching any parts to the framework othe than the stud 29 for the lever 27 I If desired the link 26 may be guided in its movement by a shoulderedscrew 35 passin through a slot 36 in the'link. This will.

fromthemandrel a ainst the holding force 'of the spring-presse lungers I9 onto the ends ofthe operators gers. The operator then grasps the record by its inside surface- Attention is called to another,a vantage ing a 'thumbiece using these twofing ers and lifts the record from the machine. It should be noted that this operation is done with onlyonehandand that the speaking-tube may be sup I (1 upon thehook 15 at the time of recor ejecting, leaving the operatorsother hand free for other purposes, such as reaching for the carton in which-the recordjs-to be ut.

. of the kind ofconstruction above described overthat previously in'use. Heretofore, it '55 has bee or contracted, or where dmanly stifi, for e' operator to-hold the usually mounted upon casters, during the operation of theejector for there was a handrs engaging the mandrel itself, while the thumb is the record-ejector, is no acumen finger-piece 30, as shown 11 necessa ,=-in some cases vwhere the" record has sh the spring-pressed lungers 19 are extraorsuch tendency, for the force ap the record-ejector reacts throng the opera: tors fin ers upon the mandrel. Inother words, t emandrel is: a fulcrum oint of the operators hand in moving the e ect r;

While the fingempiece' 30 is located at the discharge en of the mandrel, it is, however, located so far forwardly with respect thereto that there is no dan er of the record coming in contact with the gar-piece when it is bein placed uponthe mandrel.

-Since e-operators fingersare in position receive the record when it isejected it is -"now possible to impart a greater movement to the record than has heretofore beenadvisable, for it was frequently the case that the operator in ejecting would so'forcibly operate the ejector that the cylinder would ins-sas be thrown oftthe mandrel onto the floor, and

being fragilefwould, of course, break, causing in some cases an irreparable "loss.

whilerthere is here shown and described a specific embodiment of this invention it should be understood that there are many- Z other ways of carrying out the inventive idea involved and that-this invention is not limited tothespecific construction shown.
